Should I repair or replace my commercial roof?
Most commercial roofs can be repaired if the leaks are isolated and the insulation underneath is still dry. If water has soaked large areas of insulation or the membrane is failing across the roof, replacement or a restoration coating is usually the better value. We inspect the whole roof first, then give you a written repair plan and price before any work starts.
Every Commercial Roof System
From older modified bitumen roofs to single-ply TPO and PVC and metal buildings, we repair the roof systems Friendswood businesses actually have, using materials compatible with each one so repairs bond and hold.
Modified Bitumen
Asphalt-based membrane installed in layers, common on older Friendswood strip centers, offices, and churches. We repair blisters, splits, open laps, and worn flashing at walls and curbs, and patch with compatible material so the repair lasts.
TPO and PVC
White single-ply membranes with heat-welded seams. TPO reflects the hot Texas sun, and PVC holds up to grease and chemicals, which makes it a favorite for restaurants. We re-weld failed seams, patch punctures from foot traffic, hail, or falling limbs, and rebuild flashing at HVAC curbs, drains, and penetrations.
Metal Roofing
Standing seam and R-panel roofs leak most at fasteners, laps, and penetrations. We replace backed-out or worn screws and washers, seal open seams, treat surface rust, and swap out damaged panels.
Acrylic and Silicone Roof Coatings
When a roof is still sound but showing its age, a coating can stop leaks and add years of life for less than a tear-off. We always repair problem areas first, then coat.
Acrylic Coatings
Water-based, bright white, and budget-friendly. Acrylic reflects heat and works well on roofs that drain properly, including metal roofs. It is not meant for areas where water ponds.
Silicone Coatings
Silicone handles standing water and holds up to intense UV, which makes it a strong fit for flat Friendswood roofs that pond after heavy rain. Once a roof is coated with silicone, future recoats should also be silicone.
Repair First, Then Coat
Seams, flashing, and wet spots get fixed before any coating goes down, so the coating protects a sound roof. Learn more on our Commercial Roof Coatings page.

Friendswood Commercial Roof Repair FAQs
Answers to common questions from Friendswood business owners and property managers dealing with roof leaks and damage.
What type of commercial roof do I have?
Most Friendswood commercial buildings have modified bitumen, TPO, PVC, or metal. TPO and PVC are smooth, usually white sheets with welded seams; modified bitumen looks like rolled roofing with a granular or coated surface; metal is ribbed or standing seam panels. We identify it on the first inspection.
Can storms damage a commercial roof in Friendswood?
Yes. Spring hail and falling limbs can puncture TPO and PVC membranes, crack aging modified bitumen, and dent metal panels. After a storm, we inspect the roof, document damage with photos for your insurance carrier, and make repairs before water reaches the insulation.
Why does my metal roof leak around the screws?
The rubber washers on exposed fasteners dry out and crack in Texas heat, and screws can back out as panels expand and contract. Replacing worn fasteners and sealing laps fixes most metal roof leaks.
Is silicone or acrylic coating better for my roof?
Silicone is the better choice if your roof holds standing water after rain. Acrylic costs less and performs well on roofs that drain properly, including most metal roofs. We’ll recommend one based on how your roof drains.
How do you find a leak on a flat roof?
Water often travels before it shows up inside, so we trace it from the roof side: checking seams, flashing, drains, and penetrations near the leak, and probing for wet insulation.
Do you work with property managers and HOAs?
Yes. We provide photo documentation and written plans that make approvals easier, and we schedule work around tenants and residents.
